As a yoga teacher, I hear this a lot!
The irony is obvious. Being too stiff to do yoga is a bit like being "too hungry to eat", or "too tense to relax".
Yoga is not a sport, there is no required skill-set to "compete". Yoga is a practice. You win... by turning-up.
Begin where you are.
Tin Man Yoga classes are supportive classes that make allowances for stiffness, injuries or restricted mobility. The classes feature a longer warm-up phase, pose-modifications and props. Tin Man classes are full-featured classes, but recognise that depth and intensity are always the student's choice.
